Description

The McLaren M840T is a 4.0 liter, Twin Turbo, flat plane V8 engine that powers the 720s, Senna, GT,  Speedtail exotic sports cars.  Released in 2017, this is the latest upgrade to the 3.8 liter M380T found in older models like the 650s.  Even further back, the engine carries residual DNA of a LeMans Nissan Engine and turbos from a Mitsubishi EVO.

After it’s launch, the 720s quickly became popular amongst tuners, sharing drag strips with the likes of Nissan GT-R’s and Audi R8s, yet claiming a lane for itself with an identifiable exhaust note.  Our friends at EKanoo Racing were amongst the first to start testing the limits and set the benchmark by running 8.85 seconds at 159 mph, with the addition of performance downpipes, air filters a tune and MS109 fuel.
